Does seem odd you can add the knob, but not set the value.. Probably
worth asking support@ about it - there might be some specific reason for
disallowing it, or the Root node might just have been overlooked
As a workaround, could you set the initial value in the knob constructor?
n = nuke.String_Knob("foo", "foo label" "initial value")
nuke.root().addKnob(n)
